WeMod Patcher

+
+ +--- + +

WeMod patcher allows you to get some WeMod features absolutely free. This script patches WeMod, thereby removing the daily usage limit (2h), etc.

+ +## 👾 No malware? Is it safe for me? + +--- + +Yes, this is safe. This script is open-source, and you can check the code yourself. I have no intention of harming you or your computer. The script does absolutely nothing with your computer and does not require Internet access. It only affects WeMod files. + +## 💻 Does this script only work with older versions of WeMod like other unlockers? + +--- + +With this patch you will be able to use the latest version together with Pro. + +## 👀 What features will be available? + +--- + +✅ Unlimited usage time
+✅ No ads
+✅ AI Game guides
+✅ Saving mods
+❌ Connect phone
+❌ Hotkeys (hotkey functionality breaks after patch for unknown reason) + +## ❓ How to use? + +--- +1. **Clone the Repository (or just download source code)** + ``` bash + git clone https://github.com/k1tbyte/Wemod-patcher.git + cd Wemod-patcher + ``` +2. **Run the script** + ``` bash + bun install/npm install/yarn install/whatever you use + npm ./unlocker.js + ``` +3. **Follow the instructions** + +--- +## 📜 License +This project is licensed under the Apache-2.0 - see the [LICENSE](LICENSE.txt) file for details. \ No newline at end of file diff --git a/memoryScanner.js b/memoryScanner.js new file mode 100644 index 0000000..01ce815 --- /dev/null +++ b/memoryScanner.js @@ -0,0 +1,74 @@ +const fs = require("fs"); + +function findPatternInBuffer(buffer, bytesRead, signature, mask) { + const bufferLength = bytesRead + signature.length - 1; + + for (let i = 0; i <= bytesRead - signature.length; i++) { + if (isMatch(buffer, signature, mask, i)) return i; + } + + return -1; +} + + +function isMatch(buffer, signature, mask, offset) { + for (let i = 0; i < signature.length; i++) { + if (mask[i] === "x" && buffer[offset + i] !== signature[i]) return false; + } + return true; +} + +function parseSignature(signature) { + const signatureBytes = []; + let mask = ""; + + const tokens = signature.split(" "); + tokens.forEach((token) => { + if (token === "??" || token === "?") { + signatureBytes.push(0); + mask += "?"; + } else { + signatureBytes.push(parseInt(token, 16)); + mask += "x"; + } + }); + + return { signature: Buffer.from(signatureBytes), mask }; +} + + +async function patchBySignature(filePath, functionSignature, patchBytes, patchOffset) { + const { signature, mask } = parseSignature(functionSignature); + + const bufferSize = 8192; + const buffer = Buffer.alloc(bufferSize + signature.length - 1); + + const fileHandle = await fs.promises.open(filePath, "r+"); + + let filePosition = 0; + try { + while (true) { + const { bytesRead } = await fileHandle.read(buffer, 0, bufferSize, filePosition); + if (bytesRead === 0) break; + + const matchIndex = findPatternInBuffer(buffer, bytesRead, signature, mask); + if (matchIndex !== -1) { + const functionStartPosition = filePosition + matchIndex; + + // Go to patch position + await fileHandle.write(Buffer.from(patchBytes), 0, patchBytes.length, functionStartPosition + patchOffset); + + return functionStartPosition; // Return the address of the function start by signature + } + + filePosition += bytesRead; + buffer.copy(buffer, 0, bufferSize, bufferSize + signature.length - 1); + } + } finally { + await fileHandle.close(); + } + + return -1; +} + +module.exports = patchBySignature; \ No newline at end of file diff --git a/package.json b/package.json new file mode 100644 index 0000000..f774c7a --- /dev/null +++ b/package.json @@ -0,0 +1,15 @@ +{ + "name": "wemod-patcher", + "version": "1.0.0", + "main": "index.js", + "scripts": { + "test": "echo \"Error: no test specified\" && exit 1" + }, + "keywords": [], + "author": "", + "license": "ISC", + "description": "", + "dependencies": { + "asar": "^3.2.0" + } +} diff --git a/unlocker.js b/unlocker.js new file mode 100644 index 0000000..db11518 --- /dev/null +++ b/unlocker.js @@ -0,0 +1,159 @@ +const path = require('path'); +const fs = require('fs'); +const readline = require('readline'); +const asar = require('asar'); +const patchBySignature = require("./memoryScanner"); + + +const regex = /getUserAccount\(\)\{.*?return\s+this\.#\w+\.fetch\(\{.*?\}\).*?\}/g; +const asarPatch = "getUserAccount(){return this.#v.fetch({endpoint:\"/v3/account\",method:\"GET\",name:\"/v3/account\",collectMetrics:0}).then(response=>{response.subscription={period:\"yearly\",state:\"active\"};response.flags=78;return response;})}" +const signature = "E8 ?? ?? ?? ?? 85 C0 75 ??
